Icing or elevating the affected area, and removing any tight fitting jewelry, are some ways to treat swelling caused by a bee sting, according to WebMD. Icing the area works for most stings, and elevating works well for stings on an arm or leg.
If a bee sting causes tongue swelling or any other sign of anaphylaxis, seek emergency medical treatment right away, states WebMD. Treat other minor symptoms at home. Take over-the-counter painkillers such as acetaminophen or ibuprofen for pain. To calm itchiness, take an antihistamine, or apply calamine lotion or a mixture of baking soda and water. The sting area should heal in two to five days.
